Method for metamodeling unification

Abstract

The present invention relates to a method for metamodeling unification, in particular to a method for metamodeling unification to guarantee interoperability between an UML model of IEC 61850 and an UML model of IEC 61970. According to the invention, all IEC 61970 smart grid application using IEC 61850 data source easily obtains interoperability between applications and actively react to change of international standard because application developers use data by referring to a single UML IEC 61850/61970 unified model and refer to a single UML model reflecting flexibly constant modification of IEC standard, if any.

What is claimed is: 
     
         1 . A method for metamodeling unification, the method comprising:
 step (a) of receiving data from outside and defining them based on IEC 61850 and IEC 61970;   step (b) of configuring IEC 61850 and IEC 61970 objects according to level;   step (c) of identifying a data-flow scenario and identifying an object in each scenario;   step (d) of comparing and analyzing identified syntactic information; and   step (e) of unifying syntactically equivalent objects, wherein the said step (b) comprises step (b- 1 ) of transforming an object of IEC 61850 and IEC 61970 configured as input into an object model in configuration; step (b- 2 ) of transforming the object model of IEC 61850 and IEC 61970 by semantic abstraction in configuration; and step (b- 3 ) of transforming a metamodel designating abstract syntax of (b- 2 ) step.   
     
     
         2 . The method for metamodeling unification of  claim 1 , wherein the said step (a) comprises step (a- 1 ) of receiving IEC 61850 and IEC 61970 input data;
 step (a- 2 ) of IEC 61850 object configuration for configuring an object of IEC 61850 input data; and   step (a- 3 ) of IEC 61970 object configuration for configuring an object of IEC 61970 input data.   
     
     
         3 . The method for metamodeling unification of  claim 1 , wherein the said step (b) further comprises step (b- 4 ) for expanding a metamodel of IEC 61850 by configuring an object and structure of a substation while setting a semantic element describing logical node class and input data in a metaclass. 
     
     
         4 . The method for metamodeling unification of  claim 4 , wherein the metaclass configures for connection of structure of substation and IED (Intelligent Electronic Device). 
     
     
         5 . The method for metamodeling unification of  claim 1 , wherein the said step (e) unifies IEC 61850 and IEC 61970 objects which have the same meaning according to the analysis result of meaning of identified IEC 61850 and IEC 61970 objects in the comparison & analysis unit.
